Definitions
- the invention relates to a method for applying glue to a filter wrapping paper strip in a filter rod machine for the production of filters for rod-shaped smoking articles, such as cigarettes, as well as the use of a glue application device for such a method.
- filter wrapping paper is provided with a glue trace on the side facing the filter body in order to establish a connection between the filter body and the filter wrapping paper.
- the glue is in the form of beads or beads with a static distance to the edge, ie in the form of, for. B. meandering lines, applied to the filter wrapping paper. This static distance is created by a fixed position of the glue application device over the paper web.
- This object is achieved according to one aspect of the present invention by a method of applying glue to a filter wrapping paper strip in a filter rod making machine for rod smoking article filters, such as cigarettes, characterized by the steps of applying liquid glue to the cupping surface of a rotating screen roll to record from a arranged on the anilox glue distribution chamber and then applied to the filter wrapping paper strip by contact with the lateral surface of the anilox roller pressure and pressure-free.
- the invention proposes according to a second aspect to achieve the above object, the use of a glue application device with a cup having rotating screen roller and a arranged on the anilox glue distribution chamber is taken from the glue from the lateral surface of the anilox roller, for pressure-free and pressure-free application of the glue from the surface of the anilox roll on a filter wrapping paper in a filter rod machine for the production of filters for rod-shaped smoking articles, such as cigarettes.
- the glue application is thus carried out in the manner of a gravure printing system by the glue is applied without pressure and without any overpressure by wetting the paper surface on the filter wrapping paper, since the glue is simply pulled out of the wells of the anilox roller.
- a connection force is used, which arises when wetting the paper surface of the filter wrapping paper, whereby an undesirable pushing of the glue through the filter wrapping paper strip is prevented therethrough.
- the known method and the known glue application device were previously provided only for the much firmer and less porous cigarette lining paper in the cigarette manufacturing machine and thus at a completely different location within the entire process, it has surprisingly been found in a manner not obvious to those skilled in the art that This known method and this known glue application device also successfully for the gluing of the much more labile and significantly more porous filter wrapping paper without the risk of a "punch" is suitable.
- the invention is to use the known method and the known glue application device now for the pressure-free application of glue to a filter wrapping paper strip in a filter rod machine.
- the invention is particularly advantageously for the gluing of filter wrap paper strip with a high porosity between about 10,000 and about 45,000 cm 3 (cm 2 x min x kPa).
- any excess glue which may be present should be doctored off from the jacket surface of the anilox roll by means of at least one doctor blade.
- the wells are preferably arranged in a specific distribution over the width of the lateral surface of the anilox roller, in order to prevent specific traces from occurring, especially in the case of guide and deflecting rollers and other, in particular static, guides for the filter enveloping paper strip.
- Fig. 1 shows a schematic overview of the basic structure of a filter manufacturing machine, which consists of a filter trough preparation unit 1 and a downstream strand unit 2.
- the filter trough preparation unit 1 serves for the preparation of an endlessly fed filter tempette 4 and, in the illustrated embodiment, a pair of rollers 3 for continuously removing the filter tow 4 from a bale 6.
- a pair of rollers 3 for continuously removing the filter tow 4 from a bale 6.
- two air nozzles 7 and 8 which serve to loosen and spread the filter tow 4.
- the pair of rollers 3 are followed by two further pairs of rollers 9 and 11, between which there is a spray device 12 for applying plasticizer 13 on the guided between the roller pairs 9 and 11 guided filter tow 4. All pairs of rollers 3, 9 and 11 are rotated by unillustrated controllable individual drives in rotation.
- the speed of the upstream first pair of rollers 3 should be less than that of the downstream downstream pair of rollers 9, so that the filter tow 4 is stretched.
- the spray device 12 has a container 18 for receiving plasticizer liquid 13, in which a drivable by a drive motor driven removal roller 21 is immersed, from the periphery of a likewise rotating brush roller 22 continuously plasticizer liquid takes to spin against the filter tow 4.
- the thus treated and sprayed with plasticizer filter tow 4a passes from the processing unit 1 in an inlet funnel 23, which forms the entrance of the strand unit 2.
- the strand unit 2 which may also be referred to as a filter rod machine or strand machine, is used to produce filter rods from the filter tow 4a.
- the filter tow 4 a is summarized in the strand unit 2 into a strand and placed on a withdrawn from a reel 24 and provided by means of a gluing apparatus 26 with glue filter wrapping paper strip 27.
- the filter wrapping paper strip 27 and the filter tow strip 4a together reach a format tape 28 which guides both strips through a format 29.
- the format 29 causes the filter wrapping paper strip 27 to be wrapped around the already circularly shaped filter tow 4a, thereby forming an endless filter strand 31.
- This passes through in the illustrated embodiment, a Nahtplätte 32, in which the adhesive seam is solidified.
- the filter strand 31 by means of a knife apparatus 33 continuously cut off individual discrete filter rods 34, which are transferred from an accelerator 36 in a Ablegertrommel 37, in which they transferred in the illustrated embodiment from its longitudinal axial conveying direction in a transverse axial conveying direction and conveyed away on a Ablegerband 38 for further processing.
- gluing apparatus 26 is shown in more detail in a schematic longitudinal section.
- the gluing apparatus 26 has an arranged in a glue container 40 and rotatably mounted anilox roller 42 which is driven in rotation in the direction of the arrow A drawn by a controllable drive, not shown.
- the filter wrapping paper strip 27 moves in the same direction corresponding to the direction of rotation of the anilox roller 42 according to arrow A.
- the anilox roller 42 is arranged between two guide rollers 43, 44 such that the filter wrapping paper strip 27 rests on the anilox roller 42 and thereby a (albeit minor) movement change is subjected.
- Downstream of the guide roller 44 is in Fig. 2 a further deflecting roller 45 can be seen, which guides the filter wrapping paper strip 27 in the direction of the format 29 (FIG. Fig. 1 ) redirects.
- the gluing apparatus 26 comprises a block-shaped glue application element 46 containing an open tub-shaped glue distribution chamber 48.
- the glue application element 46 is arranged directly adjacent to the lateral surface 42a of the anilox roller 42, so that the glue distribution chamber 48 is directed towards the anilox roller 42 and is substantially closed by its lateral surface 42a.
- the glue distribution chamber 48 is constantly glue, which in Fig. 2 not shown in detail, wherein the glue distribution chamber 48 is constantly supplied with glue via a conveyor, not shown.
- the glue application element 46 may be substantially completely sealed against the lateral surface 42a of the anilox roller 42, so that no glue can escape from the glue application element 46. Should the glue application element 46 not be completely sealed, the leaking at the leaking glue in the glue container 40 is collected and discharged for example by means of a suction tube, not shown.
- the lateral surface 42a of the anilox roller 42 is provided with a multiplicity of cells which are not discernible in the figures and which are, in particular, crater-shaped depressions in the lateral surface 42a.
- the width of the anilox roller 42 corresponds at least to the width of the passing wrapping strip 27.
- the wells are arranged in a targeted distribution across the width of the lateral surface 42a of the anilox roller 42 to prevent specific traces of contamination, in particular the guide roller 44 and the guide roller 45 occur.
- the glue application element 46 is fastened in the illustrated embodiment to the glue container 40 by means of a holding element 50.
- the holding means 50 also serves to press the glue application element 46 against the lateral surface 42a of the anilox roller 42 to produce the aforementioned seal against the lateral surface 42a of the anilox roller 42.
- the holding means 50 preferably offers a possibility of adjusting the contact pressure and the radial distance of the glue application element 46 from the lateral surface 42a of the anilox roller 42.
- Fig. 2 can be seen, 46 two scrapers 52, 53 are arranged on the glue application element, the free end can be brought into contact with the lateral surface 42a of the anilox roller 42.
- the one doctor blade 52 is arranged at the (in relation to the direction of rotation of the anilox roller 42 according to arrow A) downstream edge of the glue application element 46; since this squeegee 52 is thus adjacent to the exit of the glue distribution chambers 48, it may also be referred to as the exit side squeegee.
- the other squeegee 53 is arranged in the illustrated embodiment on the (with respect to the direction of rotation of the anilox roller 42 according to arrow A) upstream edge of the glue application element 46 and may also be referred to as an input-side squeegee with respect to the position of the glue distribution chamber 48.
- the doctor blade may also be referred to as a positive or negative squeegee.
- a plurality of squeegees with respect to the direction of rotation of the anilox roller 42 can be arranged one behind the other.
- the anilox roller 42 rotates, its lateral surface 42a passes through the glue distribution chamber 48 and the cells present on the lateral surface 42a receive the glue present in the glue distribution chamber 48.
- the squeegee 52 ensures that any excess amount of glue which may be present is being scraped off the lateral surface 42a of the anilox roller 42;
- the other doctor blade 53 ensures that even before entry into the glue distribution chamber 48 it is possible to strip off the glue remaining on the lateral surface 42a of the anilox roller 42.
- the cells filled with glue are conveyed by continued rotation of the anilox roller 42 to a glue application zone 54 in which the wrapping strip 27 to be glued abuts against the lateral surface 42a of the anilox roller 42.
- the glue is dispensed from the cups on the lateral surface 42a of the anilox roller 42 onto the facing side of the wrapping strip 27. Since the glue is pulled out of the wells only by the bonding force that results when wetting the surface of the existing paper wrapper strip 27, the application of the glue takes place without pressure and without any overpressure on the wrapping strip 27, whereby an undesired pressing of the glue through the wrapping strip 27 is prevented.
- the described glue application on the wrapping strip 27 thus takes place in the manner of a gravure printing system.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Auftragen von Leim auf einen Filterumhüllungspapierstreifen in einer Filterstrangmaschine zur Herstellung von Filtern für stabförmige Rauchartikel, wie beispielsweise Zigaretten, sowie die Verwendung einer Leimauftragsvorrichtung für ein solches Verfahren.The invention relates to a method for applying glue to a filter wrapping paper strip in a filter rod machine for the production of filters for rod-shaped smoking articles, such as cigarettes, as well as the use of a glue application device for such a method.
Während der Herstellung von Filtern für stabförmige Rauchartikel wie insbesondere Filterzigaretten wird Filterumhüllungspapier mit einer Leimspur auf der dem Filterkörper zugewandten Seite versehen, um eine Verbindung zwischen dem Filterkörper und dem Filterumhüllungspapier herzustellen. Gewöhnlich wird der Leim in Form von Raupen oder Wulsten mit einem statischen Abstand zur Kante, also in Form von, z. B. mäanderförmigen Linien, auf das Filterumhüllungspapier aufgetragen. Dieser statische Abstand entsteht durch eine fixierte Position der Leimauftragsvorrichtung über der Papierbahn.During the production of filters for rod-shaped smoking articles, in particular filter cigarettes, filter wrapping paper is provided with a glue trace on the side facing the filter body in order to establish a connection between the filter body and the filter wrapping paper. Usually, the glue is in the form of beads or beads with a static distance to the edge, ie in the form of, for. B. meandering lines, applied to the filter wrapping paper. This static distance is created by a fixed position of the glue application device over the paper web.
Da das Filterumhüllungspapier hochporös ist, besteht die Gefahr, dass der Leim nicht nur in das Papier eintritt, sondern wegen dessen offener Struktur auch auf dessen anderer Seite wieder austreten kann, also der Leim durch das Filterumhüllungspapier "durchschlägt". Dies ist schon deshalb nachteilig, weil das optische Erscheinungsbild von solchen Produkten mit optisch sichtbaren Leimspuren nicht ansprechend ist. Da es sich bei der anderen Seite um die äußere Seite des Filterumhüllungspapieres handelt und an dieser Seite Umlenkrollen laufen und sich sonstige Führungen befinden, sind diese Umlenkrollen und sonstigen Führungen durch Verschmutzung mit Leimresten besonders betroffen, was sich auch negativ auf die Funktion der Leimauftragsvorrichtung im Besonderen und den Betrieb der Filterstrangmaschine und somit der Filterherstellungsmaschine im Allgemeinen negativ auswirkt.Since the filter wrapping paper is highly porous, there is a risk that the glue not only enters the paper, but because of its open structure on the other side can escape again, so the glue through the filter wrapping paper "breaks through". This is disadvantageous because the visual appearance of such products with optically visible traces of glue is not appealing. Since it is the other side to the outer side of the filter wrapping paper and run on this side pulleys and other guides, these pulleys and other guides are particularly affected by contamination with glue residues, which also has a negative impact on the function of the glue application device in particular and the operation of the filter rod machine and thus the filter manufacturing machine generally has a negative effect.
Es ist daher Aufgabe der vorliegenden Erfindung, ein derartiges "Durchschlagen" von auf hochporöses Filterumhüllungspapier aufgetragenem Leim zu vermeiden.It is therefore an object of the present invention to avoid such a "strike through" of glue applied to highly porous filter wrapping paper.
Gelöst wird diese Aufgabe gemäß einem Aspekt der vorliegenden Erfindung durch ein Verfahren zum Auftragen von Leim auf einen Filterumhüllungspapierstreifen in einer Filterstrangmaschine zur Herstellung von Filtern für stabförmige Rauchartikel, wie beispielsweise Zigaretten, gekennzeichnet durch die Schritte, flüssigen Leim an der Näpfchen aufweisenden Mantelfläche einer rotierenden Rasterwalze aus einer an der Rasterwalze angeordneten Leimverteilungskammer aufzunehmen und anschließend auf den Filterumhüllungspapierstreifen durch Berührung mit der Mantelfläche der Rasterwalze drucklos und überdruckfrei aufzubringen.This object is achieved according to one aspect of the present invention by a method of applying glue to a filter wrapping paper strip in a filter rod making machine for rod smoking article filters, such as cigarettes, characterized by the steps of applying liquid glue to the cupping surface of a rotating screen roll to record from a arranged on the anilox glue distribution chamber and then applied to the filter wrapping paper strip by contact with the lateral surface of the anilox roller pressure and pressure-free.
Ferner schlägt die Erfindung gemäß einem zweiten Aspekt zur Lösung der vorgenannten Aufgabe die Verwendung einer Leimauftragsvorrichtung mit einer Näpfchen aufweisenden rotierenden Rasterwalze und einer an der Rasterwalze angeordneten Leimverteilungskammer, aus der Leim von der Mantelfläche der Rasterwalze entnommen wird, zum drucklosen und überdruckfreien Auftragen des Leims von der Mantelfläche der Rasterwalze auf ein Filterumhüllungspapier in einer Filterstrangmaschine zur Herstellung von Filtern für stabförmige Rauchartikel, wie beispielsweise Zigaretten, vor.Furthermore, the invention proposes according to a second aspect to achieve the above object, the use of a glue application device with a cup having rotating screen roller and a arranged on the anilox glue distribution chamber is taken from the glue from the lateral surface of the anilox roller, for pressure-free and pressure-free application of the glue from the surface of the anilox roll on a filter wrapping paper in a filter rod machine for the production of filters for rod-shaped smoking articles, such as cigarettes.
Erfindungsgemäß wird demnach der Leimauftrag nach Art eines Tiefdrucksystems durchgeführt, indem der Leim drucklos und ohne jeglichen Überdruck durch Benetzung der Papieroberfläche auf das Filterumhüllungspapier aufgetragen wird, da der Leim einfach aus den Näpfchen der Rasterwalze gezogen wird. Hierzu wird lediglich eine Verbindungskraft genutzt, die bei Benetzung der Papieroberfläche des Filterumhüllungspapiers entsteht, wodurch ein unerwünschtes Durchdrücken des Leims durch den Filterumhüllungspapierstreifen hindurch verhindert wird.According to the glue application is thus carried out in the manner of a gravure printing system by the glue is applied without pressure and without any overpressure by wetting the paper surface on the filter wrapping paper, since the glue is simply pulled out of the wells of the anilox roller. For this purpose, only a connection force is used, which arises when wetting the paper surface of the filter wrapping paper, whereby an undesirable pushing of the glue through the filter wrapping paper strip is prevented therethrough.

Bevorzugte Ausführungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Preferred embodiments and further developments of the invention are characterized in the dependent claims.
So eignet sich die Erfindung insbesondere in vorteilhafter Weise für die Beleimung von Filterumhüllungspapierstreifen mit einer hohen Porösität zwischen etwa 10.000 und etwa 45.000 cm3(cm2 x min x kPa).Thus, the invention is particularly advantageously for the gluing of filter wrap paper strip with a high porosity between about 10,000 and about 45,000 cm 3 (cm 2 x min x kPa).
Vorzugsweise sollte nach Entnahme aus der Leimverteilungskammer und vor Abgabe an den Filterumhüllungspapierstreifen ein eventuell vorhandener überschüssiger Leimanteil mithilfe mindestens einer Rakel von der Mantelfläche der Rasterwalze abgerakelt werden.Preferably, after removal from the glue distribution chamber and before delivery to the filter wrapping paper strip, any excess glue which may be present should be doctored off from the jacket surface of the anilox roll by means of at least one doctor blade.
Ferner sind bevorzugt die Näpfchen in einer gezielten Verteilung über die Breite der Mantelfläche der Rasterwalze angeordnet, um zu verhindern, dass spezifische Spuren zu einer Verschmutzung insbesondere von Führungs- und Umlenkwalzen und sonstigen, insbesondere statischen, Führungen für den Filterumhüllungspapierstreifen auftreten.Furthermore, the wells are preferably arranged in a specific distribution over the width of the lateral surface of the anilox roller, in order to prevent specific traces from occurring, especially in the case of guide and deflecting rollers and other, in particular static, guides for the filter enveloping paper strip.

Die Filtertowaufbereitungseinheit 1, nachfolgend verkürzt als Aufbereitungseinheit bezeichnet, dient zur Aufbereitung eines endlos zugeführten Filtertowstreifens 4 und weist im dargestellten Ausführungsbeispiel ein Walzenpaar 3 zum fortlaufenden Abziehen des Filtertowstreifens 4 von einem Ballen 6 auf. Bevor der Filtertowstreifen 4 zum Walzenpaar 3 gelangt, passiert er im dargestellten Ausführungsbeispiel zwei Luftdüsen 7 und 8, die zur Auflockerung und Ausbreitung des Filtertowstreifens 4 dienen. Dem Walzenpaar 3 folgen zwei weitere Walzenpaare 9 und 11, zwischen denen sich eine Sprühvorrichtung 12 zum Aufbringen von Weichmacher 13 auf den zwischen den Walzenpaaren 9 und 11 auseinandergezogenen geführten Filtertowstreifen 4 befindet. Alle Walzenpaare 3, 9 und 11 werden von nicht dargestellten steuerbaren Einzelantrieben in Rotation versetzt. Dabei sollte die Drehzahl des stromaufwärts gelegenen ersten Walzenpaares 3 geringer als diejenige des stromabwärts gelegenen nachfolgenden Walzenpaares 9 sein, damit der Filtertowstreifen 4 gereckt wird. Die Sprühvorrichtung 12 weist einen Behälter 18 zur Aufnahme von Weichmacherflüssigkeit 13 auf, in die eine von einem nicht dargestellten Antriebsmotor antreibbare Entnahmewalze 21 eintaucht, von deren Umfang eine ebenfalls rotierende Bürstenwalze 22 fortlaufend Weichmacherflüssigkeit entnimmt, um sie gegen den Filtertowstreifen 4 zu schleudern.The filter trough preparation unit 1, hereinafter abbreviated as treatment unit, serves for the preparation of an endlessly fed
Der so aufbereitete und mit Weichmacher besprühte Filtertowstreifen 4a gelangt von der Aufbereitungseinheit 1 in einen Einlauftrichter 23, der den Eingang der Strangeinheit 2 bildet. Die Strangeinheit 2, die auch als Filterstrangmaschine oder Strangmaschine bezeichnet werden kann, dient zur Herstellung von Filterstäben aus dem Filtertowstreifen 4a. Demnach wird der Filtertowstreifen 4a in der Strangeinheit 2 zu einem Strang zusammengefasst und auf einen von einer Bobine 24 abgezogenen und mittels eines Beleimungsapparates 26 mit Leim versehenen Filterumhüllungspapierstreifen 27 aufgelegt. Der Filterumhüllungspapierstreifen 27 und der Filtertowstreifen 4a gelangen gemeinsam auf ein Formatband 28, das beide Streifen durch ein Format 29 führt. Während der Bewegung durch das Format 29 bewirkt das Format 29, dass der Filterumhüllungspapierstreifen 27 um den bereits rund geformten Filtertowstreifen 4a herumgelegt wird, wodurch ein endloser Filterstrang 31 entsteht. Dieser durchläuft im dargestellten Ausführungsbeispiel eine Nahtplätte 32, in der die Klebenaht verfestigt wird. Anschließend werden von dem Filterstrang 31 mittels eines Messerapparates 33 fortlaufend einzelne diskrete Filterstäbe 34 abgeschnitten, die von einem Beschleuniger 36 in eine Ablegertrommel 37 überführt werden, in der sie im dargestellten Ausführungsbeispiel aus ihrer längsaxialen Förderrichtung in eine queraxiale Förderrichtung überführt und auf einem Ablegerband 38 zur weiteren Verarbeitung abgefördert werden.The thus treated and sprayed with
In
Wie
Das Leimauftragselement 46 kann gegen die Mantelfläche 42a der Rasterwalze 42 im Wesentlichen vollständig abgedichtet sein, so dass kein Leim aus der Leimauftragselement 46 austreten kann. Sollte das Leimauftragselement 46 nicht vollständig abgedichtet sein, so wird der an den undichten Stellen austretende Leim im Leimbehälter 40 gesammelt und beispielsweise mithilfe eines nicht dargestellten Saugrohres abgeführt.The
Die Mantelfläche 42a der Rasterwalze 42 ist mit einer Vielzahl von in den Figuren nicht erkennbaren Näpfchen versehen, bei denen es sich insbesondere um kraterförmige Vertiefungen in der Mantelfläche 42a handelt. Die Breite der Rasterwalze 42 entspricht mindestens der Breite des vorbeilaufenden Umhüllungsstreifens 27. Bevorzugt sind die Näpfchen in einer gezielten Verteilung über die Breite der Mantelfläche 42a der Rasterwalze 42 angeordnet, um zu verhindern, dass spezifische Spuren zu einer Verschmutzung insbesondere der Führungswalze 44 und der Umlenkwalze 45 auftreten.The
Das Leimauftragselement 46 ist im dargestellten Ausführungsbeispiel am Leimbehälter 40 mithilfe eines Halteelementes 50 befestigt. Das Haltemittel 50 dient ferner dazu, das Leimauftragselement 46 gegen die Mantelfläche 42a der Rasterwalze 42 zu drücken, um die bereits erwähnte Abdichtung gegen die Mantelfläche 42a der Rasterwalze 42 herzustellen. Außerdem bietet das Haltemittel 50 bevorzugt eine Möglichkeit, den Anpressdruck und den radialen Abstand der Leimauftragselement 46 von der Mantelfläche 42a der Rasterwalze 42 einzustellen.The
Wie
Bei Rotation der Rasterwalze 42 läuft deren Mantelfläche 42a durch die Leimverteilungskammer 48 und nehmen die an der Mantelfläche 42a vorhandenen Näpfchen den in der Leimverteilungskammer 48 befindlichen Leim auf. Vor Verlassen der Leimverteilungskammer 48 sorgt die Rakel 52 dafür, eventuell vorhandenen überschüssigen Leimanteil von der Mantelfläche 42a der Rasterwalze 42 abzurakeln; im Übrigen sorgt die andere Rakel 53 dafür, bereits vor Eintritt in die Leimverteilungskammer 48 eventuell noch an der Mantelfläche 42a der Rasterwalze 42 verbliebenen Leim abzurakeln. Anschließend werden die mit Leim gefüllten Näpfchen durch fortgesetzte Rotation der Rasterwalze 42 zu einer Leimauftragszone 54 gefördert, in der der zu beleimende Umhüllungsstreifen 27 an der Mantelfläche 42a der Rasterwalze 42 anliegt. Durch diese Berührung wird der Leim von den Näpfchen auf der Mantelfläche 42a der Rasterwalze 42 auf die zugewandte Seite des Umhüllungsstreifens 27 abgegeben. Da der Leim lediglich durch die Verbindungskraft, die bei Benetzung der Oberfläche des aus Papier bestehenden Umhüllungsstreifens 27 entsteht, aus den Näpfchen gezogen wird, findet der Auftrag des Leims drucklos und ohne jeglichen Überdruck auf den Umhüllungsstreifen 27 statt, wodurch ein unerwünschtes Durchdrücken des Leims durch den Umhüllungsstreifen 27 hindurch verhindert wird. Der beschriebene Leimauftrag auf den Umhüllungsstreifen 27 findet somit nach Art eines Tiefdrucksystems statt. Somit ist es möglich, hochporöses Filterumhüllungspapier, beispielsweise mit einer Porösität bis etwa 45.000 cm3/(cm2 x min x kPa), problemlos zu beleimen.When the
